I love the plugin. It is a huge time saver but I'm getting an error.
extract() expects parameter 1 to be array, null given in /wp-includes/pluggable.php on line 216
This error occurs when gravity forms tries to send an email through the WordPress wp_mail function. This didn't cause an issue with saving the form submission just sending it. I deactivated the Root Relative URLs plugin resolved the issue but I do want to continue using the plugin.
To fix the issue and keep the plug in active I commented out the following on line 258 of sb_root_relative_urls.php
This also fixed the issue.
Sorry I can't offer more help but I just wanted to alert you to the issue so it can be fixed in future releases.
